Low drag, high speed.Louis Garneau's Course M-2 Cycling Bodysuit is designed to limit wind-catching transition ridges and maintain a compressive, confident fit. Except for a few exceptions, LG's CB Speedtech fabric is used across the M-2's entire body. LG claims the material's dimples shed drag and boost wicking, and the fabric's compressive nature helps minimize the effects of vibration-induced fatigue over the course of a long day in the saddle.The sleeves are made of CB M-2, which replicates the Speedtech's compression and aerodynamic savings, and the legs are a combination of Lazer Rev and Gladiator fabrics, which compress and cool while maintaining the general theme of aerodynamics. All four materials are given a Coldblack treatment, which reflects the sun's energy to keep you coolor. The suit is finished with LG's professional-grade 5 Motion chamois and lazer-cut arm and leg openings.
